Article Synopsis

  • Synthetic systems struggle to replicate the advanced color-changing abilities found in cephalopods and similar animals.
  • Soft machines made from flexible materials are evolving quickly and gaining new features.
  • The study details microfluidic networks that allow these machines to change color, pattern, and temperature for purposes like camouflage, and they can do so in visible and infrared light, surpassing natural organisms’ capabilities.

Article Abstract

Synthetic systems cannot easily mimic the color-changing abilities of animals such as cephalopods. Soft machines--machines fabricated from soft polymers and flexible reinforcing sheets--are rapidly increasing in functionality. This manuscript describes simple microfluidic networks that can change the color, contrast, pattern, apparent shape, luminescence, and surface temperature of soft machines for camouflage and display. The color of these microfluidic networks can be changed simultaneously in the visible and infrared--a capability that organisms do not have. These strategies begin to imitate the functions, although not the anatomies, of color-changing animals.

Solution polarity modulated electrochromic devices with tunable colored states.

Chem Commun (Camb)

School of Intelligent Manufacturing, Jiangnan University, Wuxi 214122, P.R. China.

Electrochromic devices (ECDs) hold great promise for applications in displays and smart military camouflage. However, achieving different electrochromic colored states with compatible integration into a monolithic device remains a significant challenge. In this study, we realized effective color modulation of ECDs by tuning the solvent composition, leveraging the effects of solvent polarity.

The dwarf cuttlefish, (formerly ), is a coleoid cephalopod like octopus and squid, and an emerging model organism for scientific research. Dwarf cuttlefish can change the color, pattern, and texture of their skin in milliseconds to camouflage with their surroundings and communicate with conspecifics. Their skin displays are directly controlled by the brain.

There is a need for on-site applicable, simple, cost-effective, and rapid methods for the remediation of 2,4,6-trinitrotoluene (TNT)-contaminated soil and groundwater in military storage and reclamation sites, which necessitates extensive analyses to monitor remediation. Here, α-MnO@EDA-based colorimetric methods were developed for the rapid, selective, sensitive, and on-site determination of TNT. α-MnO@EDA, synthesized by passivation with ethylenediamine (EDA) of MnO formed from permanganate with thiosulfate reduction, produces a colorimetric signal by entering into a charge-transfer interaction between the electron-rich amine groups in its structure and the electron-deficient nitro-groups of TNT.

Development of a Reflective Electrochromic Zinc-Ion Battery Device for Infrared Emissivity Control Using Self-Doped Polyaniline Films.

Electrochromic devices (ECDs) capable of modulating both visible color and infrared (IR) emissivity are promising for applications in smart thermal camouflage and multifunctional displays. However, conventional transmissive ECDs suffer from limited IR modulation due to the low IR transmittance of transparent electrodes. Here, we report a reflection-type electrochromic zinc-ion battery (HWEC-ZIB) using a self-doped polyaniline nanorod film (SP(ANI-MA)) as the active layer.

With the rapid development of infrared (IR) detection technology, the demand for IR camouflage in military reconnaissance and civilian fields is increasing. Although low-emissivity materials can accommodate high-temperature objects, they cannot allow temperature-variable objects to maintain infrared camouflage at all times in their environment. In this paper, a simple metamaterial structure is used to realize IR adaptive camouflage with a thermal switch.
